So this is the follow-up on the posting below. We put the engine to three holes up over the winter, and put on the 13 x 16 Powertec SCD prop. With two on board, WOT is 5400 rpm, and (GPS) speed is 30 mph. This is a marked improvement and we're going to leave it the way it is.

Phil T is right that something is wrong, but I think it's just the prop pitch and the engine height. The former owner seemed to have little interest in boat performance, and may have gotten a deal on whatever propeller his dealer happened to have in the shop when he reengined.
The bottom is a mess and will be sandblasted this fall, there is no top, we had two people on board and maybe ten gallons of fuel. This is really just a beach launch for us. I'm just trying to get more efficient operation - it's my wife's boat, I never drive it, and she never runs at WOT.
I'm going to buy and try Tim's 13 x 16 Powertec SCD, hopefully next week. It should help a lot, and once I get the engine raised, I'm sure I'll be happy.
Thank you all very much for your help, this is a great place to come for help!
